Fascinating info, thank you! According to Bill Bryson in A Short History of Nearly Everything (a good read), a meteor large enough to destroy us all would most likely strike our planet before being detected due to its stealth and velocity. So that's fun.
Amazing. In 1908, people witnessing the Tunguska event would have had no idea what just happened. Today, millions of people knew pretty much exactly what happened (meteor strike) within a matter of minutes and hours. What will we know in ~100 years the next time this sort of thing happens?
Meanwhile, I think it's wild that a system that was meant to check for nukes helped us figure out what was up with this meteor. Love it!! Carl Sagan would totally be in glee
You missed the part that the meteor that exploded above Russia was an intirely different one than the (much bigger) asteroid which was passing by (the one everyone was watching). We are pretty good at following and predicting paths of lartge chunks of rock, unfortunately there are a LOT small 'pebbles' like this we have not found yet.
It was a rock most likely made of ice and iron. The reason it didn't cause a lot of damage is because it exploded before reaching the ground; only small fragments made it to Earth. Those fragments weren't the cause of damage but the shockwave.
The sonic boom represents a small fraction of the total energy released which was in the form of sound waves, heat, and light. But the particular harmonics (comprised of low frequency sound) and the outward rushing of the air wave resulting from the explosion of asteroid material caused the damage to the windows and other structures.
The narrator said that it lasted more than 30 secs between entering the atmosphere and the explosion. The "10 seconds" you are referring is the time you can actually see the asteroid burning with your eyesight. Those are different things.
A "rock" comprised of iron and other metals of the estimated mass reported, combined with its speed and angle of entry would cause exactly the damage witnessed. What "mechanical object" are you referring to?
I saw 36 thumbs down & figured at least 3/4 of them post something ridiculous & conspiratorial. I found them in the last 100 posts. Way to go (you know who you are)! On the other hand my faith in humanity skyrocketed w/ some amazingly insightful & scientifically correct posts. Go humanity!
Rick Kabrx Really? at the start of the video the narrator says that NASA had promised the public that earth will not be hit...!! You are right, humanity is going!! :-D
Yes, I guess it is huge. Thank you I hadn't looked at like that. I sometimes forget that the planet is much larger than the tiny piece of Oregon that I call home.
Interesting video! This is an invitation to see an artist theory on the physics of light & time. Based on just two postulates: 1 The quantum wave particle function Ψ or probability function represents the forward passage of time itself with the future unfolding photon by photon. 2 Is that quantum uncertainty ∆×∆p×≥h/4π that is formed by the w-function is the same uncertainty we have with any future event within our own ref-frame that we can interact with turning the possible into the actual
That exploding meteorite at the moment captured in this particular video and/or other videos on dashcams etc is not 14 or 15 miles above the surface in altitude as suggested?!?
At around 3:03 you can notice that something hit the Comet just like mentioned on another videos where the happening can be shown more clearly. This one more viewing perspective that proves the strange incident.
Why not? There's a video on YT that I watched, where the time between the start of the video (the meteor was entering the frame at that moment) and the sound from the explosion's shockwave amounts to about 30 seconds. This gives a distance of about 10 000 m from the camera to the explosion (which was almost overhead). Therefore, the explosion must have occurred at least that high, i.e. 10 km or more.
Well, the second it hit the atmosphere it started to burn up, that's how this whole fireball thing works. So really that's even less then 10 seconds. Do you mean it was 30 seconds from the explosion to the point that it could be heard? Because that was more like 6 minutes.
The technology and funding possessed by NASA and other space agencies at this time aren't good enough to detect objects that small (and not enough to keep an eye on as much of the sky as would be needed); future improvements may allow us to find smaller targets such as this.
Based on (E=ˠM˳C²)∞ the Lorentz contraction of space and time is between the energy and mass. The greater the energy the greater the contraction of space and the slower time will run. Mass will increase relative to this and each ref-frame can be seen as a vortex in space formed by the rate that time flows. C² is light radiating out in all directions forming a sphere that can be squared to form the future probability. The brackets represent the boundary condition of the ref-frame within infinity!
Nice video. Marred only by announcer's repeated mispronuciation of Chelyabinsk city, something that could easily have been avoided by a quick visit to Wikipedia. He did get Tunguska right, though.
I checked, and it appears to be lens artifacts as the bolide brightens up. There might be cutting edge tech we don't know about, but I don't see why it would be exactly where needed (in the middle of nowhere) and how it would track, pin point n lock in less than 10 seconds. I've seen hundreds of meteors, including 2 bolides similar to this one (but higher n smaller) and this one's acted exactly like any other meteor, people just need to make things more 'exotic', as if it wasn't amazing enough.
Asteroid = big piece of rock orbiting a star (our sun) Meteor = piece of rock that hits a planet It is just a matter of labels, when an asteroid hits a planet we call it a meteor.
Well I hope everyone is okay in the Ural area, however this was an amazing event but it does concern me that NASA didn't expect it to hit. What if in a few years an even bigger one hits us when we aren't prepared? Probably me just being paranoid though....
Do you think the meteor that exploded in Tunguska in 1908 was 'shot down' by the Russians? When meteors encounter the atmosphere they are travelling at phenomenal speed. The friction becomes intense and the air in front of the meteor so dense it's like hitting a wall. That's why they explode. Just like any other 'shooting star'. If the Russians shot it down, where is the trail from the missile? Do you really think we have something that can hit an object travelling at 20 to 40 miles a second?
Yes, I suppose your right. People do see what they want to see, I'm guilty of that for sure. I do find it strange that Russia had Tunguska & this event, the 2 largest meteors in recorded history (I admit that I am not certain of this, but as far as I know) both of these ending with a violent explosion. What are the odds of that happening? is it commonplace for meteors to explode in the atmosphere rather than striking the Earth? I'm truly fascinated by this and appreciate your insight.
The earth mag.field is pretty strong, but it does not deflect meteors nor asteroids, it can deflect ions n plasma because of their electric charge and the meteor would be neutral. We might try to use the iron in the meteor which can be magnetised, but for a bolide travelling at that speed, it would need to be immense and very close, like a couple of meters. But we know that meteors, if small enough, burn up so there's no need, nor justification, for some far-fetched 'ray-gun' or simile.
Another obvious facts shows there's no 'interception'. Whether it was a sonic gun/ laser / or anything you can imagine, when you look at the images, from all the different angles, 1 thing is clear. After the flare, the remains of the meteor continue on the same initial trajectory. Any 'interception' would provide a force that either scatters the remains all over, or significantly deflects them. Neither is evident in the footage, confirming the well known, and well studied, air-burst model.
Increible gracias a la NASA podemos darnos cuenta de lo que ocurre en el universo!! como cuerpo celeste somos un punto de poca significancia en el universo
Thats assuming they use conventional rocket propulsion, it goes without saying if they possessed advanced technology its not something they would advertise and would seem impossible due to our conventional way of thinking.
If I were to speculate it seems likely that the asteroid was related to 2012 da14 in that the same event that caused 2012 da14 to be dislodged from the asteroid belt probably also dislodged the asteroid that entered earths atmosphere and exploded but I suspect you have already come to that conclusion.
I doubt they had the reaction time to do so. Probably the meteor shattered itself becouse of a stress internal to the rock , temperature made it unstable and kaboom. (as happens to glass when you heat it fast enought , it breaks)
NASA is know saying comet ison will not strike earth this year, however they slow down earths orbit just as ison passes by on a diagram animation. you can see this for your self on NASAs web site with ther time frame animation.
Occam's razor. Meteor explodes as consequence of well known physics or Russians just happen to have a formidable 'gun ray' in position, in the middle of nowhere, able to pin point, within seconds, an object travelling supersonically, when they couldn't even stop a cesna, from Germany, landing in Red square a few years back. Sure, anything within reason is possible, but what's most likely?
You are right but it's easy to hit it if you stay on it's way, no extreme speed is required, just launch a bunch of missile from Earth to it's route...
But there are much less police cars than there are regular cars. Thus, one can be joyful that the asteroid exploded over Russia since it was captured on so many different angles. Period.
"it struck the earth atmosphere at 40000 miles an hr" from the commentary and worked out by scientists, not a youtuber. If you check the footage, at 3.00 from first appearing to its explosion it takes 10 seconds. How long do you think it takes a person to look up, notice it, realise what it is and inform his superior to then receive the orders to fire? Can't people just accept an amazing event without having to make up stories? And where's the laser in the footage? Please.
Actually russian meteor had diffrent direction of tryiectory then DA14, russion come from sun direction at sunrise where DA14 fly at begining of night direction from south to north, if they been related in any way they would at least have same direction. Meteors are common thing, just it's smaller so it really could be random rocks as many of them fall to our atmosphere every day :) go see meteor monitoring network like PKiM PFN to see for yourself
Since this hit happened, it could only mean one thing, we are really one of the bowling pins in space. One day, one time, one moment, we could be gone before we know it. Anyways, just like the saying goes, what you don't know, won't hurt you. So fellas, enjoy every second of your stay in this lucky verdant planet...don't worry, be happy. let's hope that the bodily energy that we have now would not be annihilated, since energy could not be destroyed and would be a speck in this UNIVERSE forever !
There's a cushion of air near Earth that planes can bounce off of to travel farther on less gas. Is this thicker cushion, why meteorites blow up before they hit the ground? Why Russia again, is there an orbit-like path? Ionised path? Magnetic path?
And since you're so well informed, could you please explain why, after it flares, the remains of the meteor continue on the same trajectory, as seen from every angle in all the different footage, when, according to yr hypothesis, if hit from a different direction it should either scatter all over or be very noticeably deflected? I eagerly await the new physics you'll be able to provide.
Herp de derp,One if it broke off DA14 we would know, Two If it because of DA14 they would have said so. Why would they cover anything up? its not like it was crashing space ship.
That was crazy take a look at frames 3:30 through 3:45 You can see At the end of the bright flash from the explosion Of the meteor that the time On the dash cam is 911. The time on the UA-cam video is 333 while the total amount of time is 344. We all know that 3×3 is nine and if you add three and four and four you get 11.
I don't think it was the meteor. I think it was the United States trying to see if I miss you can reach that part of Russia since there is a nuclear base there
It's ok dear, ad hominems just show a lack of reasoned response. With 45 years in astronomy, studying cosmology n physics, a diploma in chemistry and an avid reader of science (loads of books n magazines subs), I know I've researched the subject. I gave the scientifically accepted version of how a meteor can burst before inpact, citing the well known Tunguska event, but without any explanation/refutation you called me ignorant. If you must know, that's called 'projecting'.
Fascinating info, thank you!
According to Bill Bryson in A Short History of Nearly Everything (a good read), a meteor large enough to destroy us all would most likely strike our planet before being detected due to its stealth and velocity. So that's fun.

Thank you for finally telling me how to pronounce the place! Every other video I've seen has intentionally avoided saying anything more than "Russia".
You missed the part that the meteor that exploded above Russia was an intirely different one than the (much bigger) asteroid which was passing by (the one everyone was watching).
We are pretty good at following and predicting paths of lartge chunks of rock, unfortunately there are a LOT small 'pebbles' like this we have not found yet.
Finally! I was wondering if it was the big asteroid that hit us and you're the first to answer my question. Thanks.
I think you forgot to turn the sound on. It might help.
I remembered this event...
LMdelmonte Delmonte same
It was a rock most likely made of ice and iron. The reason it didn't cause a lot of damage is because it exploded before reaching the ground; only small fragments made it to Earth. Those fragments weren't the cause of damage but the shockwave.
Give us a link if poss. I've seen about 10 to 15 different view and have not seen the thing you mention.
Where did the meteor hit earth? Have there been any photos of that?
The sonic boom represents a small fraction of the total energy released which was in the form of sound waves, heat, and light. But the particular harmonics (comprised of low frequency sound) and the outward rushing of the air wave resulting from the explosion of asteroid material caused the damage to the windows and other structures.

Please use SI-Units. Your videos aren't only watched in the US.
It's just wonderful that there were no deaths. I was expecting a few heart attacks or fatal car crashes, but nothing.
Yes, I guess it is huge. Thank you I hadn't looked at like that. I sometimes forget that the planet is much larger than the tiny piece of Oregon that I call home.
What you're seeing are lens flares, and the light from the meteor being reflected off of the grime on the windshield.
Interesting video!

excellent information, thanks guys keep you're eyes open for as.
A meteor that came from the asteroid belt?so how big does it have to be to be confused with an asteroid?
Have you considered the electro / magnetic forces?
Nicely done!
That exploding meteorite at the moment captured in this particular video and/or other videos on dashcams etc is not 14 or 15 miles above the surface in altitude as suggested?!?

Do you mean it was 30 seconds from the explosion to the point that it could be heard? Because that was more like 6 minutes.
A meteor is something that doesn't reach the ground without breaking into bits. A Meteorite is something that hits the ground.
What aspect of "official science" do you reject?
The technology and funding possessed by NASA and other space agencies at this time aren't good enough to detect objects that small (and not enough to keep an eye on as much of the sky as would be needed); future improvements may allow us to find smaller targets such as this.

The green ones or the red ones?

NIce video and explanation.......
As Carl Sagan once said:
The same technology can be used for good or evil, it is up to us to choose which one we are going to use.
Not quite as big as it used to be, but it *IS* still quite large
Nice video. Marred only by announcer's repeated mispronuciation of Chelyabinsk city, something that could easily have been avoided by a quick visit to Wikipedia. He did get Tunguska right, though.

very cool. thanks for his video.
We don't know how common exploding meteors are. But as for Russia being the target - look at a globe. The country is huge!
nothing on the object that passed through the asteroid just before it exploded then....
Asteroid = big piece of rock orbiting a star (our sun)
Meteor = piece of rock that hits a planet
It is just a matter of labels, when an asteroid hits a planet we call it a meteor.
Well I hope everyone is okay in the Ural area, however this was an amazing event but it does concern me that NASA didn't expect it to hit. What if in a few years an even bigger one hits us when we aren't prepared? Probably me just being paranoid though....
If it came in at 20 degrees, imagine if it were more direct.
It was decimated upon entering the atmosphere, a bunch of small pieces are scattered around the area.
You doubt the speed it was traveling?
Those 'objects' were not projectiles... what you were seeing was reflections/refractions of light due to imperfections and/or dirt on the wind shield.
All I could think about was the "Ass 'troyed" DVD I saw in a catalog once, I don't think it is related to stellar bodies though.
Yes it's the point that we all know of.. now what was it that shut it down is the real question ?
Do you think the meteor that exploded in Tunguska in 1908 was 'shot down' by the Russians?
When meteors encounter the atmosphere they are travelling at phenomenal speed. The friction becomes intense and the air in front of the meteor so dense it's like hitting a wall. That's why they explode. Just like any other 'shooting star'.

Tunguska?
I'd say in ~100 years there won't be any uncontrolled asteroid contacts with our atmoshpere :D
Système International d'Unités.
In other words, the International System of units.
so what exploded?
The earth mag.field is pretty strong, but it does not deflect meteors nor asteroids, it can deflect ions n plasma because of their electric charge and the meteor would be neutral.
We might try to use the iron in the meteor which can be magnetised, but for a bolide travelling at that speed, it would need to be immense and very close, like a couple of meters.
But we know that meteors, if small enough, burn up so there's no need, nor justification, for some far-fetched 'ray-gun' or simile.
It is an American funded project, however I agree it should be denoted in text, like channels such as Vsauce do.
why not? they are people as well, does it really matter that they are from a different country to you.
Another obvious facts shows there's no 'interception'.
Whether it was a sonic gun/ laser / or anything you can imagine, when you look at the images, from all the different angles, 1 thing is clear. After the flare, the remains of the meteor continue on the same initial trajectory.

Neither is evident in the footage, confirming the well known, and well studied, air-burst model.
I dont think its impossible to hit (if theres time enough), but how ineffective its gonna be.
WOW....WONDERFULL
Ask the people who uploaded those videos immediately after the asteroid hit? They would probably of witnessed it too.
Increible gracias a la NASA podemos darnos cuenta de lo que ocurre en el universo!! como cuerpo celeste somos un punto de poca significancia en el universo
Comet = an asteroid in a highly elliptical, electric orbit that discharges as it reacts with the inner solar environment.
WAY TO GO NASA!!!
"Lasted more then 30 seconds before it exploded" it was only there for like 10 seconds dude.
Thats assuming they use conventional rocket propulsion, it goes without saying if they possessed advanced technology its not something they would advertise and would seem impossible due to our conventional way of thinking.
If I were to speculate it seems likely that the asteroid was related to 2012 da14 in that the same event that caused 2012 da14 to be dislodged from the asteroid belt probably also dislodged the asteroid that entered earths atmosphere and exploded but I suspect you have already come to that conclusion.

Probably the meteor shattered itself becouse of a stress internal to the rock , temperature made it unstable and kaboom.
(as happens to glass when you heat it fast enought , it breaks)
It says in the video: It broke up into thousands of pieces.
couldn't have said it better myself :)

amazing good . abcd of space science yet to go through more.
Wow...! spectacular... and mortal! against these kind of events, governments can't do almost nothing!
Aliens :D
How come nasa didn't see this coming and warn the Russians?
It was a Bug Meteor launched from the asteroid belt around Klendathu. XD ha ha
Yeah.. Like gathering resources from other planets and such?
there are more things out there flying around people don't realize we've been very lucky not to be hit by any of them.
Thank you. It does get annoying... but wait, they used metric tons... what? It's like they combined about fifty different types of unit measurement.
Herp de derp,One if it broke off DA14 we would know, Two If it because of DA14 they would have said so. Why would they cover anything up? its not like it was crashing space ship.

One word: CROSSFIRE!
A lot of Russians record from dashboard while driving or am I wrong?.
Yes and that is a cause for concern nonetheless, meteors of that size could land and still cause damage to property and people.
I don't think it was the meteor. I think it was the United States trying to see if I miss you can reach that part of Russia since there is a nuclear base there
